[0004] 因此,公开号为CN101220928A的中国发明专利申请公开了一种名为"防眩光的LED照明装置"的发明创造,该LED照明装置具有一颗LED管芯,并设有一个复合式反射器,LED管芯设在复合式反射器的内壁上。 [0004] Thus, Publication No. CN101220928A the Chinese Patent Application discloses a inventions called "anti-glare LED lighting device", the LED illumination apparatus having an LED die, and a composite reflector is provided device, LED die is provided on the inner wall of the composite reflector. 同时,复合式反射器上还设有屏蔽隔条,LED管芯设在两个相邻的屏蔽隔条之间。 Meanwhile, the parting strip is also provided with shielding composite reflector, LED die is disposed between two adjacent barrier ribs shield. 该LED照明装置使用复合式反射器将LED管芯射出的光线反射到需要照亮的地方,并请使用屏蔽隔条将LED管芯射出的射向两侧的光线屏蔽,以避免造成眩光。 The LED illumination device using the composite reflector reflecting light emitted from the LED die where it is needed to illuminate, and to use the shielding crosspieces of light from the LED emitted toward both sides of the die shield, to avoid glare.

[0005] 但是,如图1所示,在复合式反射器2与屏蔽隔条3相邻的位置,LED管芯1射出的光线经过四次的反射才从LED照明装置中射出,这样会大大降低LED照明装置的光出射效率。 [0005] However, as shown in FIG 3 in a position adjacent to the composite reflector 2 and the shield barrier ribs, LED dies 1 emitted light was emitted from the LED illumination device 1 through the four times reflected, it would greatly reducing the LED lighting device light emission efficiency.

[0006] 假设复合式反射器2与屏蔽隔条3内壁表面对光的吸收率均为O. l,经过四次反射 [0006] Suppose composite reflector 2 and the shield 3 gutter inner wall surface of the light absorption rate are O. l, after four reflections

后,LED照明装置的光出射效率为 After, the light emission efficiency of the LED lighting device

[0007] (1-0. 1)4X100%= 65. 65% (式1) [0007] (1-0. 1) 4X100% = 65. 65% (Formula 1)

[0008] 可见,虽然该LED照明装置能有效抑制眩光,但经过四次反射后降低了LED管芯的光出射效率,造成光浪费。 [0008] visible, although the LED illumination apparatus can effectively suppress glare, but after four reflections reduce the light emission efficiency of the LED dies, resulting in a waste of light.

[0023] 在基板10的下表面也有敷铜层(图2不可见),优选地,基板10下表面的敷铜层布置整个基板IO的下表面,并且该敷铜层通过导热器件与散热装置连接,用于将LED管芯30产生的热量导走,便于LED照明装置散热。 [0023] In the surface of the substrate 10 also has a copper layer (FIG. 2 not visible), preferably, the copper layer of the lower surface 10 of the substrate arrangement the lower surface of the entire substrate IO, and the welding heat-conducting device and the heat sink copper layer by connection for conducting away the heat generated by the LED dies 30, the LED lighting device to facilitate heat dissipation.

[0024] 图2中,基板10上设有九颗LED管芯30,其中八颗位于一个同心圆上,另外一颗位于该同心圆的圆心上,并且九颗LED管芯是一次封装成型。 In [0024] FIG. 2, the upper substrate 10 provided with nine LED dies 30, eight of which are located on a concentric circle, the center located on a further concentric circle, and the nine LED die is a forming package. 当然,实际应用时,基板10的形状、LED管芯设置的位置等,均可根据实际需要设置。 Of course, the actual application, the shape, LED dies 10 disposed in the position of the substrate and the like, can be set as required.

[0025] 基板10的上表面上方设有连接器20,连接器20呈圆形,并且开设有多个通?L。 Above the upper surface of the [0025] substrate 10 is provided with a connector 20, the connector 20 has a circular shape, and defines a plurality of through? L. 参见图3,连接器20上位于每一颗LED管芯30处均开设一个通孔21,通孔21具有大致呈方形的第一部分22以及大致呈梯形的第二部分23,其中,LED管芯30可穿过通孔21的第一部分22,且LED管芯的上端面高于连接器20的上表面。 Referring to Figure 3, each of the connector 20 on a LED 30 of the die 21 each define a through hole, the through hole 21 having a substantially rectangular first portion 22 and a second substantially trapezoidal portion 23, wherein, LED dies 30 may pass through the through hole 21, the first portion 22, and the upper end surface of the LED die above an upper surface of the connector 20.

[0026] 在连接器20上方设有九个反光杯40,每一反光杯40位于一颗LED管芯的上方,反光杯40为一个空心回转体,其内壁为向内弯曲的曲面,优选地,反光杯40的内壁是二次曲面,优选地,是经过计算设计的二次曲线回转面,该回转面是根据反射定律设计,且二次曲线是椭圆的一部分会抛物线等,并且内壁是一次光学设计曲面。 [0026] In the above connector 20 is provided with nine reflective cup 40, each located one above the reflector cup of the LED die 40, a reflector cup 40 is hollow rotating body, the inner wall is inwardly curved surface, preferably the inner wall 40 of the reflector cup is a quadratic surface, preferably a surface of revolution is the result of a quadratic curve calculated design, which is based on the law of reflection revolution surface design, and is a quadratic curve parabola be part of an ellipse, and the inner wall is a The optical design curved surface.

[0027] 反光杯40的顶端为敞口,底端开设有一个通孔,即反光杯40形成一个两端敞口的腔体,LED管芯30穿过反光杯40底端的通孔伸入腔体内。 [0027] The reflective cup 40 is open to the top, the bottom end defines a through hole, i.e., the reflector cup 40 is formed a cavity open at both ends, LED dies 30 passes through the bottom of the reflector cup 40 extends into the chamber through holes in vivo.

[0028] 连接器20每一通孔21周缘附近均设有反光杯固定座,本实施例的反光杯固定座为一圈沿连接器20上表面向上延伸的凸筋25,凸筋25与反光杯40底端配合,即凸筋25的内径与反光杯40底端的外径相等,反光杯40即可固定安装在凸筋25之内。 [0028] The connector 20 near each through hole edge 21 weeks have a reflecting cup holder, a rib reflector cup holder according to the present embodiment is connected along a circle 20 on the surface 25 of the upwardly extending, ribs 25 and the reflective cup equal to 40 with the bottom, i.e. the bottom end of the rib 40 and the inner diameter of the outer diameter of the reflector cup 25, the reflector cup 40 is fixedly mounted to the ribs 25 of the. 当然,若反光杯40的底端呈椭圆形或其他形状,凸筋25相应地设置成对应的形状。 Of course, if the bottom end of the reflector cup 40 has an elliptical or other shape, ribs 25 are provided to correspond to a corresponding shape. [0029] 参见图4,本实用新型的LED管芯30位于反光杯40的底部,即LED管芯30穿过反光杯40底部的通孔伸入反光杯40内。 [0029] Referring to FIG 4, the present invention is an LED dies 30 positioned at the bottom 40 of the reflective cup, i.e., LED die 30 through the through-hole 40 extends into the bottom of the reflector cup 40 reflector cup. 在反光杯40的底部,LED管芯30的上方填充有树脂31,用于将LED管芯30密封,以保护LED管芯30。 At the bottom of the reflective cup 40, over the LED die 30 is filled with resin 31 for sealing the LED die 30 to protect the LED die 30.

[0030] 本实用新型的反光杯40内壁还可以镀有高反射膜,如使用铝、银等材料制成的反射层,以便高效地将光线反射出去。 Of [0030] the present invention also the inner walls of reflector cup 40 may be plated with high-reflective film, a reflective layer made of such as aluminum, silver and other materials to be efficiently reflected off the light.

[0031] LED管芯30射出的管芯部分射向反光杯40的内壁,反光杯40内壁将入射的光线反射出去。 [0031] LED dies 30 emitted toward the inner wall of the die portion 40 of the reflective cup, the inner wall of the reflector cup 40 is reflected off the incident light. 由于反光杯40内壁为向内弯曲的一次光学设计曲面,入射至内壁的光线经过一次反射即可反射出反光杯40外。 Since the reflector cup 40 inwardly curved inner wall surface optical design, the light incident through the inner wall of the primary reflector 40 can be reflected off the outer reflector cup. 当然,LED管芯30射出的部分光线不经过反光杯40内壁的反射,直接射向反光杯40外部。 Of course, part of the LED die 30 emits the reflected light does not pass through the inner wall of the reflector cup 40, 40 directly at the outer reflector cup.

[0032] 由于LED管芯30射出的光线最多经过一次反射即可射出LED照明光源外,假设反光杯40内壁对光线的吸收率为0. 05,LED照明光源的光出射效率即为0. 95,高于现有的LED照明光源,避免光源浪费。 [0032] Since the LED die 30 emits light can be reflected up through a LED light source is emitted outside, the inner wall of the reflector cup 40 is assumed to light absorbance of 0.05, light extraction efficiency of LED lighting is the 0.95 , higher than the conventional LED light source, the light source to avoid waste.

[0033] 并且,反光杯40为一回转体,即反光杯40内壁不具有棱边,LED管芯30射出的光线不会经过多次反射才射出反光杯40,从而大大降低光损失,提高集束组合LED照明光源的光出射效率。 [0033] Further, the reflector cup 40 is a rotating body, i.e., the inner wall of the reflector cup 40 having no edges, LED die 30 emits the light not only emitted after the multiple reflection reflective cup 40, thereby greatly reducing the loss of light and improve bundling combination of LED lamp light emission efficiency.

[0034] 此外,反光杯40设计成回转体,且反光杯40的高度远高于LED管芯30的高度,LED管芯30向四周射出的光线均经过反光杯40的反射出去,即LED管芯30向四周射出的光线经过反光杯40反射后射向需要照亮的地方,结合人的使用习惯,避免光线直接照射人眼而并不射向集束组合LED照明光源的四周,防止眩光的产生。 [0034] Further, the reflector cup 40 is designed as a rotating body, and the height of the reflector cup 40 is much higher than the height of the LED die 30, the LED dies 30 are emitted to the surrounding light reflected out through the reflector cup 40, i.e., the LED core 30 is emitted to the surrounding light through the reflector 40 to illuminate the reflective cup toward where needed, in conjunction with people's habits, to avoid direct exposure to light and are not directed to the human eye four weeks sizing compositions LED lamp, prevent glare .

[0035] 可见,通过对反光杯40内壁的设计,对LED管芯40射出的光线进行有效地管理,让光线射向需要照亮的地方,在不需要照亮的地方则通过反光杯反射进行控制,从而实现对光线进行有效地管理,达到防止眩光的目的。 [0035] Therefore, with the design of the inner walls of the reflector cup 40, of the light emitted from the LED dies 40 are effectively managed, so that the light illuminated by directed where it is needed, is reflected by the reflective cup in place need not illuminated control, in order to achieve effective management of light, the purpose of preventing glare.

[0036] 设计集束组合LED照明光源时,首先根据集束组合LED照明光源的使用环境,如作 [0036] The sizing composition designed LED illumination source, first sizing composition according to the use environment of the LED illumination light source, such as

为路灯使用,则根据司机的行车习惯、不同公路的路基情况等,规划出需要照亮的地方,然 As the lights used, according to the driver's driving habits, such as highway roadbed situation is different, plan out where needed illuminated, then

后根据光线射向的位置,设计反光杯40内壁的曲面形状,并设计LED管芯30的位置,使LED The light toward the position of the curved shape of the inner wall 40 designed reflector, the position and design of the LED die 30, the LED

管芯30射出的光线最多经过一次反射即射向需要照亮的地方,从而实现对光线的管理。 Die 30 through a maximum of the light emitted from the reflection illuminated i.e. directed where it is needed, in order to achieve the management of light.

[0037] 由于反光杯40内壁的向内弯曲的曲面,光线经过反光杯40内壁反射后并不是发 [0037] Since the curved surface 40 bent inwardly of the inner wall of the reflector, the light reflector cup 40 after the inner wall of the reflector is not made

散性地向外射出,而是依据反射定律,经过一次反射聚向需要照亮的地方,即集束组合LED Divergence of the light emitted outward, but according to the law of reflection, after one reflection where needed to illuminate the polyethylene, i.e., a combination of LED cluster

照明光源的出光角较小,也提高的集束组合LED照明光源的光出射效率。 Angle of light illuminating light source is small, a combination of improved light cluster LED lamp emission efficiency.

[0038] 回看图3,本实用新型的连接器20由耐高温材料,如聚四氟乙烯、硅橡胶、氟橡胶 [0038] Referring back to Figure 3, the present invention connector 20 by a high temperature resistant material, such as polytetrafluoroethylene, silicone rubber, fluororubber

等制成,用于隔离LED管芯30产生的热量,避免LED管芯30产生的热量对反光杯40造成影响。 Or the like, to isolate heat generated by the LED dies 30, 30 prevent heat generated by the LED dies impact on the reflector cup 40. [0039] 同时,基板10上表面敷铜层的金属导体11的面积远大于LED管芯30的面积,这样,LED管芯30产生的热量通过金属导体11迅速地横向扩散,金属导体11上的热量通过基板10中心的陶瓷材料传导至基板10底面的敷铜层,并通过底面的敷铜层传导至散热装置。 [0039] Meanwhile, the copper surface cladding layer 10 on the substrate 11 much larger than the area of ​​the metal conductor area of ​​the LED die 30, so that the heat generated by the LED dies 30 laterally diffused rapidly through the metal conductors 11, the metallic conductor 11 heat to the bottom surface of the copper layer of the substrate 10 through the center of the substrate 10 of ceramic material, and conducted to the heat sink through the bottom surface of the copper layer.

[0040] 由此可见,使用陶瓷基双面敷铜板作为基板10,能迅速地导走LED管芯30产生的热量,实现LED照明光源高效地散热,防止LED管芯30因长时间工作在高温环境下而损坏。 [0040] Thus, using the double-sided copper clad ceramic substrate as the substrate 10, can be rapidly conducted away heat generated by the LED dies 30, LED illumination source to achieve efficient heat dissipation, the LED dies 30 to prevent work at a high temperature for a long time under environmental damage. [0041] 制作集束组合LED照明光源时,根据使用情况设计好反光杯40以及LED管芯30放置的位置,然后在陶瓷基双面敷铜板的一个表面上蚀刻出金属导体ll,形成基板10。 [0041] When making sizing compositions LED lamp, according to the use and design a good reflector cup 40 placed in the position of the LED die 30, and then etched on one surface of the double-sided copper clad ceramic substrate of metallic conductors ll, the substrate 10 is formed. 接着,将LED管芯30在金属导体11相应的位置上固晶,并将连接器20固定在基板10上方点焊金线。 Subsequently, the LED dies 30 at the corresponding position of the metal conductors 11 on a solid crystal, and the connector 20 is fixed to the substrate 10 above the spot gold wire. 最后,将反光杯40固定在连接器20上,同时在LED管芯30上方填充树脂,待树脂固化后即形成集束组合LED照明光源。 Finally, the reflective cup 40 is fixed to the connector 20, while over the LED die 30 filled with the resin, curing the resin to be formed after LED lighting cluster composition. 可见,本实用新型的集束组合LED照明光源中反光杯40在集束组合LED照明光源制作过程中一次封装成型。 Be seen, the present invention compositions cluster LED lamp 40 in a reflector cup encapsulation molding compositions cluster LED lamp manufacturing process.

[0042] 当然,上述实施例仅是本实用新型较佳的实施方案,实际应用时还可以有更多的变化,例如,在多个反光杯的上周缘上设置一块连接板,将多个反光杯连接成一体,即多个反光杯一体成型;又或者,在集束组合LED照明光源光出射效率要求不高的情况下,反光杯内壁不设置高反射膜等,这些改变也是可以实现本实用新型的目的。 [0042] Of course, the above embodiments are merely preferred embodiments of the present invention embodiment, there may be more practical to change Shihai, e.g., a connection plate disposed on the peripheral edge of the plurality of reflector cup, a plurality of reflective cup integrally connected, i.e., a plurality of integrally formed reflective cup; or, in the case of sizing compositions LED lamp light emission efficiency is not critical, and the inner wall of the reflective cup high reflection film is not provided, these changes are also present invention may be implemented the new purpose.
